FIELD OF THE INVENTION

The present invention is directed to novel3-pyrimidinyl-4-yl-oxazolidin-2-one compounds, compositions containingthese compounds, the use of such compounds in the inhibition of mutantIDH proteins having a neomorphic activity and in the treatment ofdiseases or disorders associated with such mutant IDH proteinsincluding, but not limited to, cell-proliferation disorders, such ascancer.

BACKGROUND OF THE INVENTION

Isocitrate dehydrogenase (IDH) is a key family of enzymes found incellular metabolism. They are NADP⁺/NAD⁺ and metal dependentoxidoreductases of the enzyme class EC 1.1.1.42. The wild type proteinscatalyze the oxidative decarboxylation of isocitrate toalpha-ketoglutarate generating carbon dioxide and NADPH/NADH in theprocess. They are also known to convert oxalosuccinate intoalpha-ketoglutarate. Mutations in IDH1 (cytosolic) and IDH2(mitochondrial) have been identified in multiple cancer types including,but not limited to, glioma, glioblastoma multiforme, paraganglioma,supratentorial primordial neuroectodermal tumors, acute myeloid leukemia(AML), prostate cancer, thyroid cancer, colon cancer, chondrosarcoma,cholangiocarcinoma, peripheral T-cell lymphoma, and melanoma. (See L.Dang et al., Trends Mol. Med., 2010, 16, 387; T. Shibata et al., Am. J.Pathol., 2011, 178(3), 1395; Gaal et al., J. Clin. Endocrinol. Metab.2010; Hayden et al., Cell Cycle, 2009; Balss et al., Acta Neuropathol.,2008). The mutations have been found at or near key residues in theactive site: G97D, R100, R132, H133Q, and A134D for IDH1, and R140 andR172 for IDH2. (See L. Dang et al., Nature, 2009, 462, 739; L. Sellneret al., Eur. J. Haematol., 2011, 85, 457).

These mutant forms of IDH are shown to have a neomorphic activity (alsoknown as a gain of function activity), reducing alpha-ketoglutarate to2-hydroxyglutarate (2-HG). (See P. S. Ward et al., Cancer Cell, 2010,17, 225) In general, production of 2-HG is enantiospecific, resulting ingeneration of the D-enantiomer (also known as R enantiomer or R-2-HG).Normal cells have low native levels of 2-HG, whereas cells harboringthese mutations in IDH1 or IDH2 show significantly elevated levels of2-HG. High levels of 2-HG have been detected in tumors harboring themutations. For example, high levels of 2-HG have been detected in theplasma of patients with mutant IDH containing AML. (See S. Gross et al.,J. Exp. Med., 2010, 207(2), 339). High levels of 2-HG are highlyassociated with tumorigenesis.

Mutant IDH2 is also associated with the rare neurometabolic disorderD-2-hydroxyglutaric aciduria type II (D-2-HGA type II). Germlinemutations were found at R140 in IDH2 in 15 pateints having D-2-HGA typeII. Patients having this disorder also have consistently increasedlevels of D-2-HG in their urine, plasma and cerebrospinal fluid. (SeeKranendijk, M. et al., Science, 2010, 330, 336). Finally, patients withOilier Disease and Mafucci Syndrome (two rare disorders that predisposeto cartilaginous tumors) have been shown to be somatically mosaic forIDH1 and 2 mutations and exhibit high levels of D-2-HG. (See Amary etal., Nature Genetics, 2011 and Pansuriya et al., Nature Genetics, 2011).

Thus, there is a need for small molecule inhibitors of mutant IDHproteins having a neomorphic activity for the treatment of diseases anddisorders associated with these proteins.

However, salts and solvates havingnon-pharmaceutically acceptable counterions or associated solvents arewithin the scope of the present invention, for example, for use asintermediates in the preparation of other compounds of the invention andtheir pharmaceutically acceptable salts and solvates.

“Substituted” in reference to a group such as alkyl, phenyl, benzyl,heteroaryl, and heterocyclic, indicates that one or more hydrogen atomsattached to an atom within the group is replaced with a substituentselected from the group of defined substituents. It should be understoodthat the term “substituted” includes the implicit provision that suchsubstitution be in accordance with permitted valence of the substitutedatom and the substituent, and that the substitution results in a stablecompound (i.e. one that does not spontaneously undergo transformation,for example, by hydrolysis, rearrangement, cyclization, or eliminationand that is sufficiently robust to survive isolation from a reactionmixture). When it is stated that a group may contain one or moresubstituents, one or more (as appropriate) atoms within the group may besubstituted. In addition, a single atom within the group may besubstituted with more than one substituent as long as such substitutionis accordance with the permitted valence of the atom. Suitablesubstituents are defined for each substituted or optionally substitutedgroup.

The skilled artisan will appreciate that salts, includingpharmaceutically acceptable salts, of the compounds according to formula(I) may be prepared. These salts may be prepared in situ during thefinal isolation and purification of the compound, or by separatelyreacting the purified compound in its free acid or free base form with asuitable base or acid, respectively.

Pharmaceutically acceptable acid addition salts can be formed withinorganic acids and organic acids, e.g., acetate, aspartate, benzoate,besylate, bromide/hydrobromide, bicarbonate/carbonate,bisulfate/sulfate, camphorsulfonate, chloride/hydrochloride,chlortheophyllonate, citrate, ethandisulfonate, fumarate, gluceptate,gluconate, glucuronate, hippurate, hydroiodide/iodide, isethionate,lactate, lactobionate, laurylsulfate, malate, maleate, malonate,mandelate, mesylate, methylsulphate, naphthoate, napsylate, nicotinate,nitrate, octadecanoate, oleate, oxalate, palmitate, pamoate,phosphate/hydrogen phosphate/dihydrogen phosphate, polygalacturonate,propionate, stearate, succinate, sulfosalicylate, tartrate, tosylate andtrifluoroacetate salts.

Inorganic acids from which salts can be derived include, for example,hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid,phosphoric acid, and the like.

Organic acids from which salts can be derived include, for example,acetic acid, propionic acid, glycolic acid, oxalic acid, maleic acid,malonic acid, succinic acid, fumaric acid, tartaric acid, citric acid,benzoic acid, mandelic acid, methanesulfonic acid, ethanesulfonic acid,toluenesulfonic acid, sulfosalicylic acid, and the like.Pharmaceutically acceptable base addition salts can be formed withinorganic and organic bases.

Inorganic bases from which salts can be derived include, for example,ammonium salts and metals from columns I to XII of the periodic table.In certain embodiments, the salts are derived from sodium, potassium,ammonium, calcium, magnesium, iron, silver, zinc, and copper;particularly suitable salts include ammonium, potassium, sodium, calciumand magnesium salts.

Organic bases from which salts can be derived include, for example,primary, secondary, and tertiary amines, substituted amines includingnaturally occurring substituted amines, cyclic amines, basic ionexchange resins, and the like.

The pharmaceutically acceptable salts of the present invention can besynthesized from a basic or acidic moiety, by conventional chemicalmethods. Generally, such salts can be prepared by reacting free acidforms of these compounds with a stoichiometric amount of the appropriatebase (such as Na, Ca, Mg, or K hydroxide, carbonate, bicarbonate or thelike), or by reacting free base forms of these compounds with astoichiometric amount of the appropriate acid. Such reactions aretypically carried out in water or in an organic solvent, or in a mixtureof the two. Generally, use of non-aqueous media like ether, ethylacetate, ethanol, isopropanol, or acetonitrile is desirable, wherepracticable. Lists of additional suitable salts can be found, e.g., in“Remington's Pharmaceutical Sciences”, 20th ed., Mack PublishingCompany, Easton, Pa., (1985); and in “Handbook of Pharmaceutical Salts:Properties, Selection, and Use” by Stahl and Wermuth (Wiley-VCH,Weinheim, Germany, 2002).

Solvates, including pharmaceutically acceptable solvates, of thecompounds of formula (I) may also be prepared. “Solvate” refers to acomplex of variable stoichiometry formed by a solute and solvent. Suchsolvents for the purpose of the invention may not interfere with thebiological activity of the solute. Examples of suitable solventsinclude, but are not limited to, water, MeOH, EtOH, and AcOH. Solvateswherein water is the solvent molecule are typically referred to ashydrates. Hydrates include compositions containing stoichiometricamounts of water, as well as compositions containing variable amounts ofwater.

The compounds of formula (I), including salts and solvates thereof, mayexist in crystalline forms, non-crystalline forms, or mixtures thereof.The compound or salt or solvate thereof may also exhibit polymorphism,i.e. the capacity of occurring in different crystalline forms. Thesedifferent crystalline forms are typically known as “polymorphs”.Polymorphs have the same chemical composition but differ in packing,geometrical arrangement, and other descriptive properties of crystallinesolid state. Polymorphs, therefore, may have different physicalproperties such as shape, density, hardness, deformability, stability,and dissolution properties. Polymorphs typically exhibit differentmelting points, IR spectra, and X-ray powder diffraction patterns, allof which may be used for identification. One of ordinary skill in theart will appreciate that different polymorphs may be produced, forexample, by changing or adjusting the conditions used incrystallizing/recrystallizing a compound of formula (I).

The invention also includes various isomers of the compounds of formula(I). “Isomer” refers to compounds that have the same composition andmolecular weight but differ in physical and/or chemical properties. Thestructural difference may be in constitution (geometric isomers) or inthe ability to rotate the plane of polarized light (stereosiomers). Withregard to stereoisomers, the compounds of formula (I) may have one ormore asymmetric carbon atom and may occur as racemates, racemic mixturesand as individual enantiomers or diastereomers. All such isomeric formsare included within the present invention, including mixtures thereof,unless specifically indicated otherwise. If the compound contains adouble bond, the substituent may be in the E or Z configuration. If thecompound contains a disubstituted cycloalkyl, the cycloalkyl substituentmay have a cis- or trans-configuration. All tautomeric forms are alsointended to be included.

Any asymmetric atom (e.g., carbon or the like) of a compound of formula(I) can be present in racemic or enantiomerically enriched, for examplethe (R)-, (S)- or (R,S)-configuration. In certain embodiments, eachasymmetric atom has at least 50% enantiomeric excess, at least 60%enantiomeric excess, at least 70% enantiomeric excess, at least 80%enantiomeric excess, at least 90% enantiomeric excess, at least 95%enantiomeric excess, or at least 99% enantiomeric excess in the (R)- or(S)-configuration. Substituents at atoms with unsaturated double bondsmay, if possible, be present in cis-(Z)- or trans-(E)-form.

Accordingly, as used herein a compound of formula (I) can be in the formof one of the possible isomers, rotamers, atropisomers, tautomers ormixtures thereof, for example, as substantially pure geometric (cis ortrans) isomers, diastereomers, optical isomers, racemates or mixturesthereof.

Any resulting mixtures of isomers can be separated on the basis of thephysicochemical differences of the constituents, into the pure orsubstantially pure geometric or optical isomers, diastereomers,racemates, for example, by chromatography and/or fractionalcrystallization.

Any resulting racemates of final products or intermediates can beresolved into the optical isomers by known methods, e.g., by separationof the diastereomeric salts thereof, obtained with an optically activeacid or base, and liberating the optically active acidic or basiccompound. In particular, a basic moiety may thus be employed to resolvethe compounds of the present invention into their optical isomers, e.g.,by fractional crystallization of a salt formed with an optically activeacid, e.g., tartaric acid, dibenzoyl tartaric acid, diacetyl tartaricacid, di-O,O′-p-toluoyl tartaric acid, mandelic acid, malic acid orcamphor-10-sulfonic acid. Racemic products can also be resolved bychiral chromatography, e.g., high pressure liquid chromatography (HPLC)using a chiral adsorbent.

The invention includes unlabeled forms as well as isotopically labeledforms of compounds of formula (I). Isotopically labeled compounds havestructures depicted by the formulas given herein except that one or moreatoms are replaced by an atom having a selected atomic mass or massnumber. Examples of isotopes that can be incorporated into compounds ofthe invention include isotopes of hydrogen, carbon, nitrogen, oxygen,phosphorous, fluorine, and chlorine, such as ²H, ³H, ¹¹C, ¹³C, ¹⁴C, ¹⁵N,¹⁸F ³¹P, ³²P, ³⁵S, ³⁶Cl, ¹²⁵I respectively. The invention includesvarious isotopically labeled compounds as defined herein, for examplethose into which radioactive isotopes, such as ³H and ¹⁴C, or those intowhich non-radioactive isotopes, such as ²H and ¹³C are present. Suchisotopically labelled compounds are useful in metabolic studies (with¹⁴C), reaction kinetic studies (with, for example ²H or ³H), detectionor imaging techniques, such as positron emission tomography (PET) orsingle-photon emission computed tomography (SPECT) including drug orsubstrate tissue distribution assays, or in radioactive treatment ofpatients. In particular, an ¹⁸F or labeled compound may be particularlydesirable for PET or SPECT studies. Isotopically-labeled compounds offormula (I) can generally be prepared by conventional techniques knownto those skilled in the art or by processes analogous to those describedin the accompanying Examples and Preparations using an appropriateisotopically-labeled reagent in place of the non-labeled reagentpreviously employed.

Furthermore, substitution with heavier isotopes, particularly deuterium(i.e., ²H or D) may afford certain therapeutic advantages resulting fromgreater metabolic stability, for example increased in vivo half-life orreduced dosage requirements or an improvement in therapeutic index. Itis understood that deuterium in this context is regarded as asubstituent of a compound of the formula (I).

Certain compounds of the present invention were found to have improvedpreclinical properties. For example, certain compounds of the presentinvention were found to have maintained potency against mIDH1 (forexample IDH R132H and/or R132C) in biochemical and/or cellular activityassays, while at the same time improving in-vitro absorption,distribution, metabolism and excretion (ADME) properties. For example,certain compounds of the present invention were found to have reducedclearance rates in rat and/or mouse and/or human in vitro livermicrosomal stability assays. Stability in the presence of livermicrosomes is important because it can be predictive of in-vivoclearance, and therefore also be predictive of whether or not a compoundwill have an adequate systemic exposure profile in the human body toeffect the desired pharmacological response. Lower clearance rates, i.e.the more stable the compound is in the presence of liver microsomes invitro, suggests the compound is more likely to have adequate systemicexposure in humans.

When aminoalcohol, precursor of oxazolidinone, is not commerciallyavailable, it can be prepared from aminoacid 3 following the proceduresof Scheme 2. When R³=R⁴, protected aminoester 5 is treated with anappropriate Grignard reagent to give protected aminoalcohol 6 which goesthrough basic or acidic deprotection step. When R³=R⁴, protectedaminoacid 8 is converted into Weinreb amide 9 which is treated withdifferent Grignard reagents sequentially to provide protectedaminoalcohol 10. Either basic or acidic deprotection of 10 gives 11.Insertion of CO unit into 7 or 11 to provide oxazolidinone 12 isaccomplished with several reagents, including (but not limited to)triphosgene, Et₂CO₃ or N—N′-darbonyldiimidazole, as shown in Scheme 2.

wherein R² is CH₂R^(2a)R^(2b)

Oxazolidinone 12 is coupled with dihalogen-pyrimidine 13 in the presenceof NaH and the resulting 14 is treated with primary amine 15 underseveral different reaction conditions as shown in Scheme 3 to provide16.

wherein R² is CH₂R^(2a)R^(2b)

Alternately intermediate 14 can be prepared by coupling the aminoalcohol 11 and dihalogen-pyrimidine 13 in the presence of a base such asdiisopropylethyl amine resulting in intermediate 17 which can be treatedwith triphosgene in the presence of a base such as 2,6-lutidineresulting in intermediate 14.

wherein R² is CH₂R^(2a)R^(2b)

Intermediate 14 can undergo modification of functional groups on R¹, R²,R³ or R⁴ prior to transformation to compound 16 as described in Scheme3.

Mutant IDH1 R132H catalytic activity was monitored using thequantitative liquid chromatography/mass spectrometry (LC-MS) detectionof 2-HG, a product of the NADPH-dependent alpha-KG reduction reaction.

More specifically, the biochemical reactions were performed at roomtemperature in 384-well Greiner flat-bottom plates (Costar, Cat. No.781201) using a final reaction volume of 30 μL and the following assaybuffer conditions: 50 mM HEPES pH 7.4, 10 mM MgCl₂, 50 mM KCl, 1 mM DTT,0.02% BSA, 5 uM NADPH and 100 uM alpha-KG.

The final reaction mixture contained 3.3% DMSO and inhibitors withconcentrations ranging 0.02-50 μM. The IDH1 enzyme was used at a finalconcentration of 0.25 nM. Following 45 minutes incubation, the reactionmixtures were quenched by the addition of 10 μL of 16% formic acidcontaining 800 nM of 5-carbon labeled ¹³C-2-HG). The protein was thenprecipitated by the addition of 2.5 volumes of acetonitrile followed bycentrifugation (3000×g, minutes). The concentration of 2-HG in theresulting supernatants was measured by LC-MS (see below).

LC-MS method. Reaction mixture supernatants were submitted tochromatographic separation on a BiobasicAX column (2.1 mm×20 mm, 5 μmparticle, Thermo Scientific Inc.). The chromatographic mobile phaseswere A) 25 mM ammonium biocarbonate and B) acetonitrile (0.1% ammoniumhydroxide). Nicotinamide was eluted at 1 ml/min using a 85-5% B gradientover 0.9 minutes (Agilent 1200SL LC system, Thermofisher LX-4autosampler) and analyzed by multiple reaction monitoring (MRM) on aAPI4000 QTrap mass spectrometer (ABSciex, Framingham, Mass.) in thepositive electrospray ionization (ESI+) mode. The mass transition for2-HG and ¹³C-2-HG were 147→129 and 152→134, respectively. The relativeresponses (2-HG/¹³C-2-HG) were measured at varied inhibitorconcentrations and used to calculate inhibitory IC50 values (normalizedIC50 regression curves).

R132 Protein Expression and Purification.

IDH1 R132H was cloned into the pET47b vector using the restriction sitesXmaI/XhoI which yields an in frame, N-terminal His₆ site cleavable withPrescission protease. This plasmid was transformed into Rosetta™ 2 (DE3)(Novagen) cells. In shake flasks, 8 L of cells were grown in TerrificBroth (Teknova) (plus kanamycin 50 μg/mL and chloramphenicol 34 μg/mL)at 37° C. to an OD₆₀₀ of 0.8 and protein expression was induced byaddition of IPTG to a concentration of 0.20 mM. The cells weresubsequently grown for 18 hours at 18° C.

The cells were homogenized in Lysis Buffer with protease inhibitors(cOmplete EDTA-free protease inhibitor tablets (Roche), 1 tablet per 50mL of buffer), DNAse, and to 200 μM PMSF and lysed in a Microfluidizer.After lysis, Triton X-100 was added to 0.1% and stirred at 4° C. for 30minutes.

The cleared lysate was loaded onto 2×5 mL HisTrap FF crude columns (GE),washed extensively with Lysis Buffer until the A₂₈₀ stabilized andeluted with Ni Elution Buffer. Peak eluted fractions were concentratedto 30 mL, EDTA was added to 1 mM and GST-Prescission protease was addedto 3 U/100 μg of protein. The sample was dialyzed against 2 L DialysisBuffer I (MWCO 50 kDa) for 6 hours at 4° C. then dialyzed against 2 L ofDialysis Buffer II for at least 6 more hours. GST-Prescission cleavedsample was rocked with Glutathione Agarose Beads, spun down and then thesupernatant was loaded through a 5 mL HisTrap HP column and the flowthrough was collected.

Flow through was then diluted with ice cold 20 mM Tris pH 7.4 and 1 mMTCEP until the conductivity dropped to less than 5 mS/cm (a roughlythree fold dilution). This sample was then flowed through a HiTrap Qcolumn and the flow through was concentrated to 10 mL and loaded onto anequilibrated 26/60 Superdex 200 column using SEC Buffer as the mobilephase. Peak fractions were collected, concentrated and aliquoted.

The results of the mutant IDH1 biochemical assay (mIDH R132H) are givenin Table 40. Some of the examples were run in the assay multiple timesand therefore the IC50 values are expressed as a range of activity.

Fluorescence Biochemical Assay

The IDH1 (R132H) mutant catalyzes the reduced form of NADP+ (NADPH) andα-ketoglutarate (α-KG) to form nicotinamide adenine dinucleotidephosphate (NADP+) and R (−)-2-hydroxyglutarate (2HG). The reaction canbe monitored kinetically by following the oxidation of NADPH to NADP+which is measured using fluorescence, excitation at 355 nm and emissionat 530 nm. Reactions were monitored using the Perkin-Elmer Envision,Model 2101. More specifically, the biochemical reactions were performedat room temperature in 384-well Greiner flat-bottom plates (Cat. No.781076) using a final reaction volume of 20 μL and the following assaybuffer conditions: 50 mM HEPES pH 7.5, 10 mM MgCl₂, 1 mM DTT, 0.02% BSA,0.02% Tween-20, 10 μM NADPH and 100 μM α-KG. The final reaction mixturecontained 2.5% DMSO and test compounds with concentrations ranging0.0000008-25 μM. The IDH1 (R132H) enzyme was used at a finalconcentration of 10 nM. Curve fitting for dose response IC50determinations was done using a 4-parameter logistic model:y=min+((max−min)/1+(x/IC₅₀)^(slope)).

The results of the fluorescense biochemical assay (mIDH R132H) are givenin Table 40. Some of the examples were run in the assay multiple timesand therefore the IC₅₀ values are expressed as a range of activity.

The IDH cellular assay consisted of two side-by-side comparatorassays: 1) 2HG oncometabolite detection assay using LC-MS (See MutantIDH1 biochemical assay for LC-MS detection details) and 2) Cellproliferation assay to monitor off-target killing of cells and tonormalize 2HG level change.

IDH1 cellular screens were run with the HCT-116 cell line (expressendogenous level of IDH1mut R132H, available from Horizon DiscoveriesX-Man isogenic human cell lines, catalog #HD104-013). The cells weregrown in DMEM (LONZA Cat#12-540F) with 10% Fetal bovine serum (Gibcocat#10099) and 1× non-essential amino acids (NEAA LONZA cat#13-114E).Panel assays were run periodically to test compound activity in celllines with different endogenous mutations—HT1080 (IDH1mut R132C,EMEM+10% FBS), SNU-1079 (IDH1mut R132C, RPMI+10% FBS+1% sodiumpyruvate), and SW1353 (IDH2mut R172S, RPMI+10% FBS+1% sodium pyruvate).

The assay process was as follows:

Day 1: cells were seeded in 384-well plates (Corning Cat#3707) intriplicates for both the cell proliferation and 2HG assay, and incubatedat 37 C, 95% Rh, 5% CO2 overnight.

Day 2: compounds were serially diluted 1:3 (10 point dilution from 10 mMsolutions in DMSO) and delivered to the cell assay plates via acousticdispenser, with final concentration ranging from 30 uM to 1.5 nM. Theplates were returned to the incubator after treatment and incubated for48 hours.

Day 4 Proliferation assay: CTG (cell titer-glo, Promega part #G755B) wasadded to the assay plates and luminescence signal was read on the platereader.

Day 4 2HG assay: Extraction sample preparation consisted of aspiratingall media from the assay plates, adding 70 ul of 90% methanol in water,dry ice incubation for 15 minutes, centrifuging at 2000 rpm for 30 minto ensure all particulates have settled, and transferring 30 ul of thesupernatant into LC-MS ready plates. LC-MS analysis followed.

Certain compounds of the invention were tested in the IDH CellularAssay.

Determination of Metabolic Stability in Liver Microsomes—Method I

The in vitro metabolic stability assay was performed in a 96-well glassplate with shaking incubation at 37° C. A 10 mM DMSO stock solution ofthe test compound was sequentially diluted 1:1000 to yield a finalreaction concentration of 1 μM in 50 mM KPi. Immediately prior to thestart of the experiment, respective animal or human liver microsomes(male Sprague-dawley rat, male CD-1 mouse, or pooled human livermicrosomes) were diluted in 50 mM KPi to 1.25 mg/mL liver microsomalprotein. 30 μL of the 10 μM solution containing the test compound wasadded to 120 μL of microsomal protein for 150 μL enzyme-compoundmixture. The reaction was initiated by adding 150 μL of cofactorsolution (2 mM NADPH, 4 mM MgCl in 50 mM KPi) to the enzyme-compoundmixture, and the final reaction concentrations are listed in the tablebelow.

At 0, 5, 10 and 30 minute time points in the reaction, reaction aliquots(50 μL) were removed and the reactions were terminated by the additionof acetonitrile (150 μL) containing a mass spectrometry internalstandard (1 μM glyburide). The samples were centrifuged and thesupernatants analyzed by LC-MS/MS for quantization of remainingcompound. The percentage of compound remaining, relative to 0 minutes,was used to estimate in vitro elimination-rate constant (k_(mic)) whichwas used to calculate in vitro metabolic clearance rates.

Analysis of the samples was performed on a high performance liquidchromatography-tandem mass spectrometry (LC/MS) system consisting of aThermo TSQ Quantum Ultra mass spectrometer, an H-ESI ion source, aCTC-HTS Pal autosampler, and an Agilent LC Pump. Samples were separatedon an XTerra C18 column, 2.1×20 mm, 3.5 μm using the fast mobile phasegradient outlined below.

The injection volume was 10 μL. Compoundswere detected using the Thermo QuikQuan software which collectsintensity data for all fragments related to the molecular weight of thetest compound. After collection of the raw data, the software identifiesand integrates the peak of the strongest intensity.

Each microsomal elimination rate, k_(mic), was based on a 4-pointelimination curve tested in singlet. LC-MS/MS raw data for a reactionplate was returned as integrated analyte peak areas for the testcompound and internal standard used in the quench solution for thereaction to enable use of analyte:internal standard peak area ratios(PARs) for all data comparisons. The reaction time point (e.g. 0, 5, 20or 30 minutes) was plotted versus the natural logarithm of percent testcompound remaining relative to 0 minutes (based on relative PAR). Theslope of this clearance plot, k_(mic), was used to calculate the invitro half-life, t_(1/2), in order to focus on linear reaction kinetics,whenever possible, data points representing <10% test compound remainingwere generally omitted from the definition of the clearance plot slope.

Determination of Metabolic Stability in Liver Microsomes—Method II

The in vitro metabolic stability assay was performed in a 96-deep-wellplate with incubation at 37° C. 10 mM DMSO stock solution of the testcompound was diluted 1:20 in acetonitrile, followed by an additional1:10 dilution in 100 mM potassium phosphate buffer (KPi) to yield afinal reaction concentration of 1 μM. Immediately prior to the start ofthe experiment, respective animal or human liver microsomes (maleSprague-dawley rat, male CD-1 mouse, or pooled human liver microsomes)were diluted in 100 mM KPi to 1.25 mg/mL liver microsomal protein. 290μL of cofactor solution (1.7 mM NADPH, 1.7 mM UDPGA, 3.4 mM MgCl in 100mM KPi) was added to 200 μL of microsomal protein for a final volume of490 μL. The reaction was initiated by adding 10 μL of the 50 μM testsolution to 490 μL of microsomal protein for a final volume 500 μLenzyme-compound mixture.

The final reaction concentrations are listed in the table below:

Final Reaction Concentrations Final reaction Reaction componentconcentration Potassium phosphate (KPi) 50 mM buffer, pH 7.4 MgCl₂ 2.0mM NADPH 1.0 mM UDPGA 1.0 mM Liver microsomes 0.5 mg/mL Test compound1.0 μM DMSO (test compound solvent) 0.01% (v/v)

At 0, 5, 15 and 30 minute time points in the reaction, reaction aliquots(75 μL) were removed and the reactions were terminated by the additionof 50:50 acetonitrile/methanol solution (75 μL) containing a massspectrometry internal standard (0.5 μM glyburide). The samples werecentrifuged at 4000 RPM for 10 minutes. Supernatants (15 μL aliquots)were transferred to a new plate where each well contains 90 μL ofdeionized water. The supernatants solution were analyzed by UPLC/MS/MSfor quantitation of parent remaining compound under multiple reactionsmonitoring mode (MRM) in positive mode. The percentage of compoundremaining, relative to 0 minutes, was used to estimate in vitroelimination-rate constant (k) which was used to calculate in vitrometabolic clearance rates.

Analysis of the samples was performed on an ultra-performance liquidchromatography-tandem mass spectrometry (UPLC/MS/MS) system consistingof an AB Sciex Qtrap 5500 mass spectrometer, AB Sciex Turbo V ionsource, Waters Acquity Sample Organizer, Waters Acquity Column manager,Waters Acquity Sample manager, and a Waters Acquity Binary SolventManager. Chromatographic separation of analyte and internal standard wasachieved using a reverse phase C-18 column (50×2.1 mm, 1.7 μm, AcquityUPLC BEH C-18) with the following UPLC mobile phases and elutiongradient:

UPLC mobile phase A: 0.25% formic acid in 5% methanol; mobile phase B:0.25% formic acid in 95% water.

Compounds were detected using Analyst1.5.1 software which collects intensity data for all fragments relatedto the molecular weight of the test compound. After collection of theraw data, the software identifies and integrates the peak of thestrongest intensity.

Each microsomal elimination rate, k, was based on a 4-point eliminationcurve tested in duplicates. LC-MS/MS raw data for a reaction plate wasreturned as integrated analyte peak areas for the test compound andinternal standard used in the quench solution for the reaction to enableuse of analyte:internal standard peak area ratios (PARs) for all datacomparisons. The reaction time point (e.g. 0, 5, 15 and 30 minutes) wasplotted versus the natural logarithm of percent test compound remainingrelative to 0 minutes (based on relative PAR). The slope of thisclearance plot, k, was used to calculate the in vitro half-life.

${{Half}\mspace{14mu}{life}\mspace{14mu}\left( t_{1/2} \right)\mspace{14mu}\left( \min \right)} = \frac{- 0.693}{k}$The intrinsic clearance value, CL_(int) (expressed as μL/min/mgmicrosomal protein) calculation is shown below:

${CL}_{int} = {\frac{0.693}{t_{1/2}} \cdot \frac{V}{M}}$Where V=the incubation volume (mL) and M=the microsomal protein contentin the incubation (mg)
